2 Plug the other end of the cord into an RJ-45 wall outlet or external hub that is connected to a

twisted-pair Ethernet network.

After you start up the server, you need to conﬁgure the software for your network

connection. Your network administrator can provide the necessary information. You can also

get help conﬁguring your network software using Mac Help (in the Help menu). For

information on networking products you can use with your Macintosh Server G4, go to the

Macintosh Products Guide at www.apple.com/guide

Maximizing Ethernet Performance

Your server performs best when the Ethernet port to which it is attached is set to auto-

negotiate. Work with your network administrator to verify this setting.

If you connect your server directly to a conﬁgurable Ethernet switch, have your network

administrator disable spanning tree on that port. Otherwise your server may duplicate the

AppleTalk address of another computer on the same network and both network connections

may become unreliable.

Important The duplex mode of an Ethernet link to a switch is not detected if the switch’s

port is not auto-negotiating. Your server detects the appropriate speed but defaults to half-

duplex. If the switch’s port at the other end of the link is conﬁgured for full-duplex, a large

number of late events can occur on the link. Set the switch’s port to auto-negotiate where

possible. If this isn’t possible, then set the switch’s port to half-duplex. For more information,

see the documentation that came with the Ethernet hub.
